There's been an ongoing, carbon copy, series of events that has taken place in every Manny Pacquiao fight since he fought Oscar De La Hoya.

That procession has included Pacquiao's opponents appearing very intent on upsetting the eight-time world champion and vowing to train like never before. Pacquiao's opponents have been brash, confident and aggressive..... well until they actually stepped into the ring.

Ricky Hatton, Miguel Cotto, Joshua Clottey, Antonio Margarito and Shane Mosley all spoke at length about using their natural size advantages and power to overwhelm the Filipino star and then proceeded to duck, dodge, run and sometimes crash to the ground once they stepped inside the ring.

I can't guarantee the outcome, but I can tell you this: Pacquiao's next opponent, Juan Manuel Marquez, won't do any of those things. In fact, Marquez has the boxing intelligence, style and heart needed to beat Manny Pacquiao.

2.Marquez's Intelligence

The sport of boxing is just as much of a thinking man's game as Chess (although I can't see Bobby Fischer lacing up a pair of gloves).

Juan Manuel Marquez doesn't posses great power, speed or agilility, but he does posses one of the greatest minds the sport has ever seen.

Fight after fight Marquez's opponents have spoken about his ability to neutralize his opponents' game plan and adjust throughout fights.

Manny Pacquiao should be the first in line to talk about the great intelligence and in fight adujustment making, that makes Marquez so special.

In each of their prior two meeting Pacquiao was able to attain early success, knocking Marquez down three times in the first fight and once early in the second, but was later neatralized as Marquez was able to effectivily adjust during the fight and take away Pacquiao's strengths.

If Marquez is able to defeat Pacquiao, it wont be because of superior strength, quickness or technique, rather it will come from a superior game plan and boxing intelligence.

1. He's Done It Before

OK, maybe not officially, but in my book Juan Manuel Marquez sports a 2-0 record over Manny Pacquiao.

Yes, Pacquiao knocked Marquez down three times in the first round of their opening fight, but Marquez precedeed to dominate each and every round with his superior boxing intelligence and counter punching. The fight ended in a draw, but I saw it as a victory for Marquez.

In their second bout, once again, the occurrence of an early knock down saved Pacquiao as Marquez seemed to win the majority of the rounds.

Now, the fact that I believe Marquez won two fights, that were more then three years ago, doesn't mean I believe he will beat Pacquiao come November 5th. What it does mean is that Marquez has a style and skill set that has given Pacquiao major problems in the past.
